NOTES AND QUFAilES. 4G7 



Yellow Wagtail in Bedfordshire in November, — On November 11th, 

 whilst my son and I wero walking around the Sewage Farm at Newn- 

 hani, wo observed a YoUow Wagtail ; it was either an adult female or a 

 bird of the j'ear. I have never previously known this species occur 

 in this county later than the end of September ; numbers remain 

 as a rule until the second or third week of that month, but soon 

 after all have passed southwards. I have notes, September 19th, 

 1909, of numbers being seen at Blunham ; September 29th, 1907, 

 of solitary birds seen at Copley and Great Barford ; on the same 

 date, in 1912, one at Newnhani ; and on September 23rd, 1911, one at 

 Shefford. When such belated migrants as the above instance are 

 observed, there is always the doubt that some injury has been the 

 means of preventing their leaving this country. I spent some time 

 in watching this particular Wagtail, and I came to the conclusion 

 that, although apparently fully active when on the ground, it was 

 reluctant to take wing, and it allowed us to approach to close 

 quarters. — J. Steele Elliott. 



PISCES. 

 Meaning of "Skull Slyce." — Many kinds of fish are enumerated 

 in the Household Accounts of the ancient family of Lestrange of 

 Hunstanton (Norfolk), which fortunately are preserved from 1519 to 

 1578. Among the kinds mentioned is one called the " Skull Slyce," 

 which at present has not been identified ; Mr. Hamon le Strange, 

 the present owner of these singular manuscripts, also finds the word 

 to be spelt Sculleslyes, and Skulk Slyce in one passage. The prefix 

 " Skull " or " Scull " probably denotes the Plaice ; Skolla and 

 Sandskcidda are Swedish names for this species, and Skulder 

 Danish, but the second word " Slyce " is a complete puzzle, and 

 assistance in explaining it would be welcome. — J. H. Gurney 

 (Keswick Hall, Norwich). 



GASTROPODA. 



BehaTiour of Chiton Ruber. — An example of this mollusc, closely 

 attached to the shell of a living Anomia cphippium, obtained at 

 Weymouth, was placed in an aquarium on October 1st, 1915. It 

 was observed almost every morning that the Chiton had shifted 

 during the night to a different part of the shell, though it was never 

 seen to move in the daytime. During the night of its eighty-first day 

 of residence in the aquarium it quitted the shell of the Anomia and 

 settled upon that of a contiguous Anomia. On the 150th night it 

 returned to the first shell, where it remained for onlv a few davs>
